IPC: B65B39/04
Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To prevent the residence of a liquid caming into an air pipe accompanying exhaust operation by providing in an air exhaust pipe, an operation value made to swing freely to either stop or release air flow. SOLUTION: A liquid to be injected into a bottle fills a tank 1. A bottle A into which the liquid is to be injected in this condition is automatically raised by other suitable equipment. When the bottle is being raised, the inside 3 of the mount part of the bottle A is pushed up from the bottom opposing the pressure of a coil spring 4. As a result, the inner cylinder 3 goes up creating a gap between the bottom of the inner cylinder 3 and the valve seat 6 in the air exhaust pipe 7. Simultaneously, a window 9 in the inner cylinder 3 also goes up and is exposed in the tank 1. Because of this, the liquid in the tank 1 comes into the inner cylinder 3 from the window 9 to fill the bottle A passing between the bottom of the inner cylinder 3 and the valve seat 6.  Simultaneously with the injection operation, the air in the bottle A goes up in the air exhaust pipe 7, pushes up an operation valve 8 and is discharged from the top end of the air exhaust pipe 7 to the outside. Also in many cases, the liquid went up with the air within the air exhaust pipe 7 is returned to the tank 1.

Title: Trouble position searching system of digital transmission line
Inventor: TAKASAKI YOSHITAKA
IPC: H04B17/40
Filed: 1983-03-11
Abstract: PURPOSE:To detect a trouble position with one operation by measuring the code error rate of a corresponding repeating section at every repeating point and measuring the code error rate of the whole of a line in a receiving terminal station. CONSTITUTION:A transmitting terminal station 1 converts an original code (a) to a parity code (b). After this parity code is converted to an AMI (alternate mark inversion) code (c), it is transmitted from a transmitter 2 to a transmission line 3. If an error shown by a dotted line in Fig. (d) is generated while the AMI code (c) is transmitted through the transmission line 3, a repeater 4 detects this error and registers it and encoding it again so that the AMI rule is satisfied for the next section, and the code is transmitted. Thus, in the next section, a code error rate of only this section can be detected. Meanwhile, the code error rate of the whole of the line is detected with parity check by returning the code to an original code (f) in a receiving terminal station 5. At each repeating point, the number of code error is transmitted from a trouble signal transmitting circuit 6 when it exceeds a prescribed limit.

Abstract: PURPOSE:To facilitate reproduction of the three-dimensional image of an object set in a kinetic state by performing the pulse-lighting of coherent light in a time less than the repeated response period of an image pickup means or spatial light modulation means. CONSTITUTION:Assuming that a time required for the driving of the whole matrix picture element arranging type liquid crystal element 130 is set as T1, and such control that an optical shutter 111 is controlled so as to be set in a transmission/nontransmission state periodically is applied, and the time width of the transmission state is set as T2, and repeated cycle as T, the repeated cycle T is set at a value larger than the driving time T1 of the liquid crystal element. In the transmission period T2 of the optical shutter, a pattern signal of interference fringe is written on a CCD camera 128, and simultaneously, a part of the pattern signal is transferred as a video signal. In a residual period(T-T2). the optical shutter 111 is set in a nontransmission cycle, therefore, no pattern signal is written on the CCD camera 128, and a written signal is sent out as the video signal. In such a way, the coherent light can be put on in a time less than the operating period of the image pickup means.
